(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

27. Use the parametrization x = tcost, y = tsint of the

Archimedean spiral to find the arc length of the first full turn

of this spiral (corresponding to 0 <= t <= 2∏ ).

2. Relevant equations

3. The attempt at a solution

I use onenote and a tablet, so my exact attempt in in the pdf attached..

View attachment 27.pdf

Im not sure where I went wrong on this one. It looks correct to me.

The answer key shows.

1/2 [ t√(1 + t^{2}) + ln ( t + √{1 + t^{2}})] | 2∏, 0
